Height-Adjustable Labeler

Linear motor automatically adjusts height of container infeed right at the application station.

Height Adjustable Labeling Machine

WLS, a ProMach brand, introduced an innovative height-adjustable labeling option for its popular VR-72 labeler. This first-of-its-kind solution automatically adjusts the height of the conveyor, and thus the containers, to effectively change the label height right at the point of application when conditions call for it. The high-speed VR-72 can be programmed for a label height for one entire batch or programmed to dynamically adjust the height of each label applied.

When equipped with the height-adjustable labeling option, the VR-72 primarily runs vials and bottles containing liquid pharmaceuticals, biotech products, nutraceuticals, personal care products, cosmetics, and other consumer goods. According to WLS sales engineer Harry Anderson, there are a couple of scenarios where this heigh-adjustable capability is useful. One scenario might involve an injectable drug product that must be administered in varying concentrations. For Batch A the health professional or consumer may need to add some other solution to a fill line, preprinted on the label, that is exactly X millimeters from the bottom of the vial. But for Batch B, that solution must be added to a fill line that is Y millimeters from the bottom of the vial. Without the adjustable-conveyor feature, two different labels would have to be inventoried, one printed with a fill line for Batch A and one printed with a fill line for Batch B. But with the height-adjustable menu-driven VR-72, the same label can be used for both batches and still the fill line will be exactly where it needs to be for both batches. Not only does that reduce cost, it simplifies inventory and improves production efficiencies.
